The works of the Lord are so worthy of remembrance, and the heart of man is so prone to forget them, that various methods are needful to refresh our memories, for the glory of God, our advantage, and that of our children. God gave orders for preparing this memorial.
The priests with the ark did not stir till ordered to move. Let none be weary of waiting, while they have the tokens of God's presence with them, even the ark of the covenant, though it be in the depths of adversity. Notice is taken of the honour put upon Joshua. Those are feared in the best manner, and to the best purpose, who make it appear that God is with them, and that they set him before them.
It is the duty of parents to tell their children betimes of the words and works of God, that they may be trained up in the way they should go. In all the instruction parents give their children, they should teach them to fear God. Serious godliness is the best learning. Are we not called, as much as the Israelites, to praise the loving-kindness of our God? Shall we not raise a pillar to our God, who has brought us through dangers and distresses in so wonderful a way? For hitherto the Lord hath helped us, as much as he did his saints of old. How great the stupidity and ingratitude of men, who perceive not His hand, and will not acknowledge his goodness, in their frequent deliverances!
